Manual URL re-directs

[cliff here]

Mornin' listmates

I'm trying to think through a task I got the other day, and it seems fairly
simple however, I'm not sure what the correct tool for the Job is. Let me
break down the scenario.

I have three systems that users access for a web app, all three are
identical ie.

www.application-one.com
www.application-two.com
www.application-three.com


We are constantly flipping users between they are told to access because of
problems are maintenance etc. , and the powers that be (Management) want
there to be a single URL and make the manual redirection on the back end so
the users don't see it. They think it's embarrassing to the client (and it
is) that we're constantly having to switch them due to system problems. So
before I go down a possibly more complicated route; I'm hoping there is
something quick and easy within Apache to accomplish this. Please let me
know if you have any suggestions or any additional information I should
provide.

Thanks guys!
